To (LZ/Z LUI/1,0m, L't may concern:

Be it known that I, JOI-IN HETTRICH, a citizen of the United States, anda resident of Grand Island, in the county of Hall and State of Nebraska,have made certain new and useful Improvements in Corn-Harvesters, ofwhich the following is a specification.

My invention is an improvement in cornharvesters, and consists incertain novel constructions and combinations of parts hereinafterdescribed and claimed.

Referring to the drawings forming a part hereof, Figure l is a side viewof my improved harvester. Fig. 2 isa central longitudinal section of thesame. Fig. 3 is a rear elevation. Fig. 4 is a vertical transversesection on the line 4 4 of Fig. 1. Fig. 5 is a plan view of the base ofthe frame. Ybig. 6 is a detail of the cornstalk-ejecting rollers. Fig. 7is a transverse section of the husking-rollers, showing the arrangementof the shield. Fig. 8 is a detail sectional view of the connection ofthe teeth with the shaft. Fig. 9 is a detail perspective view of a partof the tongue, showing the guiding means. Fig. l0 is a perspective viewof a tooth, and Fig. 1l is a similar view of the bracket supporting therod for raising and lowering the frame, and Fig. 12 is a detail sectionon the line l2 12 of Fig. l.

In the practical application of my invention, I provide a frame A,comprising a base composed of the side bars (L, the cross-bars (L, and acentral bar (L2, the central bar being extended rearwardly from theframe to form a tongue (L3. At the rear end of the tongue is across-piece (L4, connected by suitable braces (L5 with the tongue andupon the cross-piece is arranged a seat (L6, and doubletrees (L7 aresecured to the tongue in advance of the crosspiece. lThe base issuitably braced by the braces (L8, extending between the side and thecross-bars and between the tongue and the rear cross-bar.

A grain-wheel w11 of ordinary construction is pivoted in the bifurcatedlower end of a shaft (L20, journaled in bearings (L21'on the tongue, andthe upper end of the shaft is provided with a crank-arm or rudder (L22,hinged thereto and retained in its adjusted position by means of thetoothed quadrant (L23, secured to a bracket on the tongue.

Uprights (L21, secured to the base, support the upp er longitudinal bars(L25, the said bars being connected together by cross-bars (L2G througha part l face thereof worm-wheels b3,

. braces c", projecting and being suitably braced by the diagonal braces(L77.

Upon each side of the front of the machine are secured dividing-boards(L10, the ends of the front cross-bar being extended beyond the sidebars to aiiord an attachment for the said dividing-boards, and attachedto the eX- tended ends of the side bars are brackets (L17, extendingbackwardly from the extended ends and being secured to the side bars bythe bolts (L28. The brackets are spaced apart from the side bars t`oprovide an opening for receiving the power-wheels B.

The front of the machine is approximately nine feet wide, and secured atpoints three feet from the corners thereof are intermediatedividing-boards (L11, having the form shown in Fig. 5 and comprising abase portion (L12, provided with the forwardly-proecting points (L13(L14,v the dividing-boards being provided with rearwardly-extending arms(L15, secured to the front cross-bar by the bolts (L16.

Upwardly-extending brackets (L29 are secured to the side bars (L and tothe brackets (L17 upon each side of the machine, the brackets comprisingspaced parallel members, one of which is provided with rack-teeth (L30.

Power-wheels B are arranged between the side bars and brackets, thewheels being secured to a shaft b, having loosely mounted upon the endsthereof pinions t', meshing with the rack-teeth, the pinions beingintegral with spiders b2, having upon the outer engaged by a worm b4upon a shaft b5, journaled in a bracket t, secured to the uprights, theshaft being provided with a handle 67 for convenience in manipulatingthe same. It will be understood that the above-described construction isthe same on both sides of the machine. l

A shaft C is journaled in bearings on from the front of the havingsecured to the outer end thereof a pinion c of relatively smalldiameter. A sprocket-wheel c2 of relatively large diameter is securedupon a studshaft c', journaled on the braces slightly above and to thefront of the shaft C. A sprocket-chain c3 passes around a sprocketwheelt8 of relatively large diameter and rigid with the power-wheel andaround the sprocket-wheel c2, the upper run of the chain engaging thesprocket-wheel c to impart romachine, the shaft IOO tation to the shaftC in a direction the reverse to lthat of the power-wheel.

saaao@c nut d, resting upon the frame. The opposite end of the carrieris supported by a roller The shaft C is provided with longitudinal C121,secured to a shaft el, journaled in the series of perforations c4, theseries being arranged at angular distances of one hundred and twentydegrees from each other and intended for the reception of pins c(integral with teeth c5, the teeth being provided with shoulders c7,engaging the periphery of the shaft, and the pins cG havingscrew-threaded ends 015, engaged by nuts c on the opposite side of theshaft. The teeth c are of the form shown in Figs. 1, 2, and l0,comprising the portion 010 and the hooked portion c, the outer face ofthe hooked portion conforming to the periphery of a circle whose centeris the center of the shaft C. rhe teeth are in three series and arearranged along the entire longitudinal extent of the` shaft C, asclearly shown in Fig. 4. They are rectangular in cross-section and areplaced with the widest dimension in a vertical plane, being arrangedupon the shaft a suitable distance apart to receive the stalks of cornbetween them and to strip the ears therefrom.

It will be evident from the peculiar arrangement of the hooked portionof the teeth that they will retain the stripped corn and carry it aroundthe wheel to the upper side thereof, since the hooked portion when itengages the ears will be inclined upwardly `and will prevent the cornfrom rolling off the same. A bar 012 is arranged upon the front face ofeach of the series for the purpose of steadying the series, the barbeing secured to the teeth in any suitable manner.

An endless carrier D is arranged within the frame for receiving the cornfrom the teeth, the carrier being supported upon the rollers d d d2,secured to the shafts di d* d5, journaled within the frame and providedupon the 'outer ends with sprocket-wheels do (ZX dy, over which passes achain d for constraining the rollers to move in unison. The endlesscarrier is driven by a chain d2, passing over a sprocket-wheel t ofrelatively small diameter, secured to the power-wheel, and over a secondsprocket-wheel f 15, secured to a studshaft f1, journaled at the rear ofthe frame. A sprocket-wheel dz on the shaft d4 is engaged by the upperrun of the chain, thus driving theupper run of the carrier rearwardly.

A second endless carrier D is arranged with its lower run in parallelismwith the upler run of the endless carrier D, the carrier beingrelatively short and arranged adj acent to the upper end of the carrierD. The carrier D is supported at one end by a roller 112, arranged upona shaft (Z13, the ends of the shaft being engaged by arms on the yoke d,whose body portion dw extends upwardly lthrough a sliding bearing in theframe and is screw-threaded, as atdl, and engaged by a frame at the rearof the machine, the outer end of the shaft being provided with agearwheel d, meshing with a gear-wheel 123 upon a shaft d2. Asprocket-wheel X25 is secured to the shaft d2 outside of the gearwheeland is engaged by a chain d10, passing over a sprocket-wheel e0 upon ashaft e, extending the full width of the machine and having securedthereto a corrugated roller e.

The roller e/ forms one of a series of pairs of rollers forming astalk-ejecting device E, the device comprising three pairs of corrugatedrollers journaled in apair of plates @15, adjustably secured to theframework by means of slots el in the upper edge of the plate, engagedby pins 622 in the frame, and a series of perforations 623 in the loweredge of the plate, likewise engaged by pins @24 in the frame. Thestalk-ejecting device comprises the shafts e, e2, e3, e4, c5, and e,provided with corrugated rollers and having upon the outer endsgear-wheels e7, provided with deeply-cut teeth e8, whereby the rollersmay move apart from each other to some extent without getting out ofmesh. The gearwheel on the shaft e meshes with the gearwheel on theshaft e2, the shaft e being driven by the chain dw, before mentioned.The gear-wheel e7 of the shaft e3 meshes with the gear-wheel e123 on theshaft d2 and with the gear-wheel el on the shaft c4, which in turndrives the shafts e5 c through the intermeshing gear-wheels c7 on saidshafts.

The shafts e, e3, and e6 are provided with spring-pressed slidablebearings e9, as clearly shown in Fig. 6. The plate c25 isslotted at elto receive the bearing e, and a spring 52 is arranged between thebearing and end of the slot. The bearing e for the shaft e is movable intwo directions, the plate being provided with an angular slot c25,having a spring arranged in each arm and engaging the bearing.

Husking-rollers F are supported below the endless carrier D and paralleltherewith, the rollers being arranged in sets of oppositely-rotatingrollers fj, and the rear ends of the rollers are reduced in size, as atf2, to provide a space large enough to allow the passage of bits ofcornstalk which may be broken off when the ears are snapped from thestalk. Each end of the roller is provided with shafts 4, projectingtherefrom and engaging perforations in upper and lower bars f7 f,mounted in bars f3 f5 in the frame. A bevel-gearfS is secured to eachroller above the upper bar, the bevel-gears of the rollers f If beingoppositely-arranged with respect to each other and each meshing with abevelgearf9 on a sliaft f10,journaled in bearings in the frame, theshaft being provided at its outer end with a pinion f, meshing with ISOj, therefrom, the endless the pinion f 12 on the shaft the rear of theframe. Guards j, comprising arc-shaped plates, are arranged between thepairs of rollers, whereby to guide the corn into the grip of the same.

When the snapped corn is dropped upon the rollers, the husk is seizedand strippedfrom the-ear, the ear sliding down the rollers and onto anendless tally below the rollers and supported upon rollers 7i h',secured to the shafts h2 71,3, journaled in the frame and driven by asprocketchain h, passing over sprocket-wheels d", dw, hx, and gx, uponthe shafts d4, d5, h3, and g2.

The husks are passed downward between the husking-rollers onto anendless carrier G, arranged above and to the rear of the endless carrierH. The carrier G is supported upon rollers g g, secured to the shafts g2g3, journaled in the frame, and driven by the engagement of thesprocket-chain h4, previously described, with a sprocket-wheel gX on theshaft g2.

A transverse endless carrier K is arranged at the rear of the machinebeneath the rear end of endless carrier H for receiving` the corncarrier K being supported by rollers 7c 7c', secured to the shafts k2lf3, ournaled in the frame and driven by means of a sprocket-chain let,engaging a sprocket-wheel c upon the shaft k3 and receiving power from asprocket-wheel m on the shaft m, journaled in brackets m2, proj ectingfrom the frame, the shaft m be'ng in turn driven by a belt m3, engaginga pulley m4 thereon and a pulley m5 upon a shaft m6, extendingtransversely of the machine, and provided on its opposite end with apinion m7, driven by an idler m8 from the pinion f1?. The husked cornmay be received directly f 16, journaled in i from this endless carrieror may be elevated to the side of a wagon bymeans of an inclinedelevator M, arranged adjacent to the end of the conveyer K andprojecting upwardly at an angle therefrom. The elevator M comprises anendless carrier m, supported by a roller m10, secured to the shaft m12,journaled in a frame comprising the side bars m14 connected in anysuitable manner, and a roller m11 on the shaft m, upon which the frameis rotatably mounted.

The endless carrier M may be elevated and depressed by means of the ropeN, secured to the outer end thereof and passing through a pulley n andsecured to any suitable portion of the machine. A shield O, of wirenetting or other suitable material, is arranged above the framework toprevent the ears of corn from being thrown too far to the rear. Theshield O is supported by a bracket o, arising from the upper portion ofthe machine.

In operation my improved harvester is pushed through the field, beingguided by the grain-wheel onthe tongue and in such manner that threerows of corn are engaged carrier H, arranged horizonby the frontthereof, the dividing-boards serving to straighten up the leaningstalks.

The teeth receive the stalks of corn between them, the distance betweenthe teeth being suhicient to allow the stalk to pass, but not the ear ofcorn, the latter being snapped off and carried upward by the teeth whichdeliver onto the endless carrier D. The endless carrier elevates theears of corn and drops them onto the reduced portions of thehusking-rollers. The husk is torn from the corn by the husking-rollersand dropped upon the husk-conveyer G, by which it is' delivered to therear of the machine. The corn slides down the rollers until it reachesthe endless carrier H, which delivers it to the transverse carrier K,from whence it is taken by the inclined elevator M and dropped into thewagon. i

One of the principal features of my invention is the arrangement of thehooked portion of the teeth to conform with the arc of the circle havinga radius equal to the length of the teeth. This arrangement tends tothrow the snapped ear against the body of the teeth and prevents them'from rolling off at the front thereof. At the lower end of thehusking-rollers and spaced apart therefrom is a guard P to prevent theears from falling over the end of the elevator.

It will be noticed from inspection of Figs. 1 and 6 th at the rollerscomprising the stalkejecting device are arranged in an arc around thedelivery end of the conveyer D, the first pair of rollers being arrangedapproximately in line with the upper run of the conveyer, the secondpair being arran ed adjacent to the periphery of the rear ro ler of theconveyer, and the third pair being arranged below the second pair insuch posit-ion that the ears falling from the end of the conveyer musttravel over the said rollers in their passage to the husking-rollers. Bythis arrangement all of the bits of stalk remaining with the snappedears are removed therefrom and ejected from the machine. The snappedears in passing around the delivery end of the conveyer are constrainedto travel in contact with'a part of the rollers of the ejecting deviceand after dropping from the con- .veyer are constrained to travel overthe remaining rollers in order to reach the husking device.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
